About 400 people have been arrested in the latest protest in Canada over higher university tuition fees.

Weeks of protests in Quebec have at times turned violent. The provincial government last week passed emergency legislation meant to end Canada's most sustained student demonstrations ever.

Protesters on Wednesday night threw objects at police in Montreal as a peaceful march fell apart. Police encircled the thousands of protesters and squeezed them into a tighter space.

Arrests were made in Montreal, Quebec City and Sherbrooke.

Quebec's premier, Jean Charest, has refused to roll back the tuition fee hikes of C$254 (£158) per year over seven years. Quebec has the lowest tuition rates in Canada, and they would remain among the country's lowest.
